Application led November 11, 1907. Serial No. 401,681.

To aZZ whom 'it may concern:

Be it known that I, ULYssEs GRANT Mc- QUEEN, a citizen of the UnitedStates, residing in the city of New Rochelle, in the county ofWestchester, in the State of New York, have invented certain new anduseful Improvements in Windows, of which the following is aspecification, reference being had to the accompanying drawings, forminga part hereof.

This invention relates to windows which being arranged to swing upon'central vertical axes, must be lifted above the window'4 stops of theframe sills, before they can be swung. In such windows the sash head isusualIy pivoted upon a follower which is raised and lowered with thesash, and at the lower end is pivoted upon a stud which is seated orbears upon the sill and with which coperate the devicesv by which thesash is lifted to clear the sill stop.

It is with the lower pivot and sash lifting devices that the inventionis particularly concerned and it has for its object to provide animproved construction which can be readily applied to the window, shallbe easily operated, the retention of the window in any one of severalpositions without danger of breakage of parts should the window beforced by the wind or by persons ignorant of the mechanism to move, andshall not be liable to be put out of order from any ordinary cause.

The invention will be more fully explained hereinafter with reference tothe accompanying drawings in which it is illustrated as embodied in aconvenient and practical structure, and in which- Figure 1 is a view infront, inside elevation of a window equipped with the presentimprovement, the Window sash and frame being shown. Fig. 2 is anenlarged detailed view in horizontal section on the plane indicated bythe line 2 2 of Fig. l. Fig. 3 is a detail view in vertical sectionthrough the lower sash member, showing the sash lifting devices inelevation. Fig. 4 is a detail view in vertical section through the sashhead and upper frame member. Fig. 5 is a detail view partly in verticallon itudinal section through the lower sash mem er, showing the sashlifting devices and detent in elevation.

The window frame c and the sash Z) may be of any desired size and shapeand of any suitable construction,` the sash being movable shall beefficient, shall provide for vertically to a Vlimited extent in theframe and swinging upon a vertical central axis, being suitablyprovided, as clearly shown in Fig. 2, with right and left rabbeted edgesb', b2, to coperate with corresponding rabbeted stops a and c2 of theframe. 3 is pivoted centrally, as at o, to a follower d which may rise,with the sash, into a recess @Xin the frame head a4.

The lower sash member b4 is recessed, preferably from the inner face andat the lower edge, to receive the sash lifting devices with which theinvention is particularly concerned, a bearingplate e, for the inner endof the shaft hereinafter mentioned, being secured to the inner'face ofthe recess, while the recess is closed by a cap plate f, having at itslower edge an inclined or beveled flange f to conform to the inclinationof the sill. The plate f is also provided with an extended bearing f4for the shaft g, which, outside of theplate, carries the operatinghandle or lever g. At g2 the shaft may be squared to receive a cam Ztand at its inner end g3 it is bluntly pointed to serve as a center punchfor determining the osition of the inner bearing plate e, after t e capplate f has been tted to the sash. The cam h is rovided upon its faceadjacent to the cap p ate f, as

A shown by dotted lines in Fig. 5, with a stop ZL', which coperates withthe upper and lower stops f2 and f3, as also shown by dotted lines inFig. 5, on the inner face of the cap plate j, to prevent the cam frombeing turned too far in Veither direction. A stationary stud i, whichforms the lower pivot for the sash, is mounted iixedly on a foot i',secured to the sill a5, the stud i rising, with a snug working iit,through the flange f. In the upper end of the stud i is mounted ananti-friction Wheel or roller 'Z2 upon which the cam his adapted tobear. In the iiange f', near one end thereof, is mounted a detent Wheelor roller 7c which projects downward slightly beyond the lower lface ofthe flange f and is ada ted to cooperate with a track Z secured to t esill and provided with a series of depressions or recesses Z', Z2, etc.,into which'the wheel or detent 7c may enter, if the sash is loweredslightly when swung from its closed position, and thereby retain theWindow in yany one of several different positions.

In the operation of the devices described, it being assumed that thewindow is in its closed position, the handle or lever g is grasped andmoved so as to partially rotate the cam 7L which ,bearing upon theroller t2 in the pivot stud t, 1s turned easily and lifts the having arecess, of a sash until its lower edge is raised above the sill stop aand the sash is then swung upon the vertical axis of the two pivots cand fi. If it is desired to retain the sash in one position or another,the handle g is moved slightly to permit the sash to drop somewhat,thereby permitting the detent c to engage one or another of the recessesZ', Z2, etc., in the track Z. The recesses are preferably shallow andconcave, so that, if the sash is compelled to move by the wind or by thepressure of the hands, the detent wheel c will roll out of the recess,raising the sash slightly, and thereby permit the sash to swing to itsclosed position without danger of breaking any of the parts.

It will be understood that the details of construction may be variedwithout departing from the spirit of the invention.

I claim as my invention:

l. The combination with a window frame and a sash arranged to swingtherein of a stationary pivot stud fixedly mounted upon the frame, alifting device carried by the sash and arranged to coperate with thestud, and means to actuate the lifting device.

2. The combination with a window frame and a sash arranged to' swingtherein of a stationary pivot stud fixedly mounted upon the frame, a.wheel mounted in the stud, a cam carried by the sash and arranged tobear upon the wheel, and means to partially rotate the cam.

3. The combination with a window frame and a sash arranged to swingtherein of a sta-4 tionary pivot stud iiXedly mounted upon the frame, acam carried by the sash and arranged to coperate with the stud, stops tolimit the movement of the cam in opposite directions and means topartially rotate the cam.

4. The combination with a window frame and a sash arranged to swingtherein and cap plate for said recess, a stationary pivot stud fixedlymounted upon the frame, a shaft having a bearing in the cap plate, a cammounted on the shaft and arranged to coperate with the stud, and ahandle for the shaft.

5. The combination with a window frame and a sash arranged to swingtherein, of a stationary pivot stud fixedly mounted upon the frame, alifting device carried by the sash and arranged to co Y erate with thestud, means to actuate the ifting device, and a detent carried by thesash and arranged to engage the frame to hold the sash in position.

6. The combination with a window frame and a sash arranged to swingtherein, a stationary pivot stud iixedly mounted upon the frame, alifting device carried by the sash and arranged to coperate with thestud, means to actuate the lifting device, a concentric track with deressions mounted on the frame and a roller etent carried by the sash toengage said depressions.

7. The combination with a window frame and a sash arranged to swingtherein and having a recess, a cap plate for said recess having a bottomflange with an aperture, a pivot stud mounted u on the frame to entersaid aperture, a shaft aving a bearing in the cap plate, a cam mountedon the shaft and arranged to coperate with the stud, a handle for theshaft, a detent wheel carried by the flange of the cap plate and aconcentric track with depressions secured to the frame.
